We love making oatmeal balls with leftover oatmeal, and more recently oatmeal bakes (pretty similar to oatmeal but you bake in the oven instead of stovetop).
Oatmeal balls are an awesome/fun finger food and easy to eat for breakfast, as a snack, or sticking in a lunch box.
Make a ball with the leftover oatmeal (after its in the fridge it is usually cold and sticky and holds its shape well) then roll it in the coconut flakes or hemp hearts.
We pack our oatmeal with goodies like:
hemp hearts
chia seeds
ground flax seeds
cinnamon
pepitas
pure maple syrup
nut butter
coconut flakes
vanilla extract
pinch of salt
